Reactive extraction of special metabolites is of interest, since the technique can provide higher distribution coefficients than pure physical extraction. In addition, very polar carboxylic acids can only be extracted by using extractants such as organophosphorus compounds or high molecular weigth amines. In this paper, the extraction of typical metabolites such as penicillin G and α amino acids is discussed in regard to the nature of the extractant and modifier used.
Die Gewinnung von Alkoholen, aliphatischen und aromatischen Carbonsauren, Aminosauren und Penicillinen aus komplexen Medien sowie die Trennung chemisch ahnlicher Verbindungen durch Extraktion aus komplexen Gemischen wird beschrieben.
Recovery of low-molecular organic compounds from complex aqueous mixtures by extraction.This article considers the recovery of alcohols, aliphatic and aromatic carboxyl acids, amino acids, and penicillins from complex media as well as the separation of chemically similar compounds by extraction from complex mixtures.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
